The embedded controller that we developed in the FairPlay project was used to control heat production with solar mirrors (TCT) to a PCM buffer, as a demonstrator for Stichting Anpak’n. We managed to warm the buffer above 60 degrees in February, and at its max of 75 degrees in March 1. The heat was used to pre-heat CV and tap water. In May the buffer was often back at max temperature at noon, i.e. much more heat was produced than could be stored.
